Perfect timing. I am literally on my way to HF to buy the blades. Will try a package to see how they work. For those whose fabric won't cut cleanly, are your cutting only a single layer of fabric or multiple layers? I never cut more than one layer at a time. Yes, I know this is more time consuming, but I feel I have better control of my cuts when I only do one layer at a time, so this is what I do. This is totally my preference, not right nor wrong...to each his own, as they say. Will let you know how I like the HF blades. I only wish they made them in the 28mm size as this is my preferred rotary cutter size. Oh well, we can't have everything in life, can we? Have a wonderful day and keep on quilting! :-)
